Hello All,
I have a harddisk with a loose partition at the end. I like to make this
available to FreeBSD, however I cannot get fdisk to work. Maybe someone can
help? I'm not sure if this is the right list to post, so if I'm wrong please
direct me to the correct one (but I couldn't find a more appropriate list).
Here the output of fdisk:
---------------------------fdisk start----------------------------------------
******* Working on device /dev/rwd0 *******
parameters extracted from in-core disklabel are:
cylinders=1647 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=1647 heads=16 sectors/track=63 (1008 blks/cyl)
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 0 is:
sysid 4,(Primary DOS with 16 bit FAT)
start 63, size 41265 (20 Meg), flag 0
beg: cyl 0/ sector 1/ head 1;
end: cyl 40/ sector 63/ head 15
The data for partition 1 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 41328, size 1023120 (499 Meg), flag 80
beg: cyl 41/ sector 1/ head 0;
end: cyl 1023/ sector 63/ head 15
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
---------------------------fdisk end----------------------------------------
I like to turn the 2nd partion to the 306MB I should have availabe. Using a
calculator (..., anyone used NT's DiskManager?) I determined the startaddress
and size, however I coudn't get fdisk to let this partition start at cilinder
1024, even when explicitly specifiying the beginaddress:
---------------------------fdisk start---------------------------------------
The data for partition 2 is:
<UNUSED>
Do you want to change it? [n] y
Supply a decimal value for "sysid" [0] 165

---------------------------fdisk end----------------------------------------
What to do? Something simple I assume :-(
Some notes on this machine:
a 486DX/33Mhz, ISA bus only. BIOS does not understand harddisks greaters as
500MB (no large or LBA modes), but that's no problem I assume as I don't run
Dos. FreeBSD correctly identifies the harddisk as a 810MB one.
Thanks,
Berend.
